ELEKCTROMECHANICAL BOTTLE OPENER Filed Aug. 28. 1931 2 Sheets-Sheet 2 M ATTYORNEY Patented Oct. 18, 1932 PATENT OFFICE p ERNEST VELASQUEZ, on NEW ORLEANS, LOUISIANA ELECTROMECHANICA; BOTTLE OPENER Application filed August as, 1931. Serial no. 560,045.

The invention relates to an automatic bottle opener and more particularly to an electromechanical bottle opener.

The primary object of the invention is the I '5 provision of a device of this character wherein a support accommodates a plurality of bottles and the covers or tops therefor being controlled on the closing of electric circuits having arranged therein electromagnets so '-10 that when a switch to the circuit of each 1 5 ing of the selected bottle, the device being applicable for use in laboratories, dental ofiices, surgical quarters, or in any place where a number of bottles are to be used for access to the contents thereof, thereby re- 2'0 lieving an attendant or person from this manual act of opening the bottles by hand, the switches for closing the circuit to operate electromagnets for controlling the opening of the covers or lids to the bottles '25 being arranged conveniently to an attendant or person.

A further object of the invention is the provision of a device of this character, wherein the covers or tops of bottles will be auto- 30 matically controlled for the opening and closing of such bottles selectively.

A still further object of the invention is the. provision of a device of this character which is simple in construction, thoroughly 35 reliable and eificient in operation, neat and attractive in appearance and inexpensive to manufacture and mstalll With these and other objects in view, the

invention consists in the features of construce0 tion, combination and arrangement of parts 5 in the claims hereunto appended.

In the accompanying drawings Figure 1 is a fragmentary elevation of an instrument'stand of that type employed in dental offices showing the device constructed in accordance with the invention supported thereby and also diagrammatically the electric equipment in association therewith.

Figure 2 is a perspective view of the switch box with push button switches for controlling individually the respective circuits of the device.

Figure 3 is an enlarged vertical transverse sectionalview showing in. detail the electromagnetand by full lines the bottle cover or top' in closed position and by dotted lines in raised or opening position.

Figure 4 is fragmentary top planview of the bottle rack andadjunct parts.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

' Referring to the drawings in detail, A designates a stand which is of conventional form andis in character an instrument stand for dental offices, while superimposed therefor provided in said base, which latter is preferably inthe form of a block preferably made'from wood although the same may be made from any other suitable material.

-Rearwardly of each bottle 11 supported upon the base 10 is a vertical housing 13 in the upper portion of which is rotatably sup- 1 ported a pulley 14 over which is trained a chain 15, one end of which carries a weight 16, whilethe other end is connected with the -movable core 17 of an electromagnet 18, this being arranged in an open electric circuit including the wires 19 which are connected in parallel with'the electric house wiring circuit 20. In each circuit having the wires19 -is arranged a switch 21 manually closed through the medium ofa push button 22,

these switches 21 being located within a switch box 28 carrying at its top the buttons 22 and this box is adapted to be conveniently placed upon a foundation so that the push button 22 can be actuated by foot. On closing the respective circuits including the wires 19 the cores 17 of the magnets 18 will be drawn thereinto on energizing said magnets so as to shift the chain 15 to rotate the pulley 14 against the resistance of the weight 16 carried by said chain.

Each pulley 14: has thereon an arm 2% carrying a lid or top 25 for the bottle 12 adjacent thereto, the cover or top 25 being normally in closing position upon the bottle and when the magnet 18 is energized and the core 17 drawn therein the cover or top 25 will be raised from the mouth of the bottle 12 to opening position, that is, from the position shown by full lines in Figure 3 to that shown by dotted lines in said Figure 3 of the drawings. hen the magnet 18 is deenergized by the opening of the circuit theretothe weight 16 becomes active to reverse the movement of the chain 15 and thus the rotation of the pulley will lower the cover or top 25 onto the mouth of the bottle 12 for the closing thereof.

It will be readily seen that manual opening of the bottles is entirely eliminated as such bottles can be opened automatically through pressing a selective switch button 22 which closes the switch 21 and thus the circuit to a magnet 18 is closed for the automatic raising of the cover or top 25 from the mouth of the bottle under selection thereof so that access may be had to its contents and thereby relieving manual labor for this purpose.

The device is readily useful in laboratories, dental offices, surgical quarters, hospitals, or other like places or institutions.

The housing 13 has a rounded upper end 26 and this end is cutaway at 27 to accommodate the swing-of the arm for the opening and closing of the cover or top 26 as will be obvious.

What is claimed is 1. In a device of the kind described, a base, a plurality of bottles on said base, a pulley for each bottle supported by said base, .a chain trained over the pulley, a weight on one end ofthe chain, electromagnets arranged in the base and having movable cores connected with said chains, normally open electric circuits having arranged therein the mag nets and normally open electric switches, a box for inclosing the switches and having push buttons controlling said switches, and covers connected with the pulleys and normally closing the bottles and automatically raised when the switches close the circuits for energizing the electromagnets to draw their cores therein.

2. In a device of the kind described, a plurality of bottles, covers for said bottles, a pul- ERNEST VELASQIJEZ.
